Amnesia XXL Autoflowering
This section features a selection of marijuana seeds that, given their morphological and growth characteristics, offer great results indoors. All of them are perfectly suited to indoor growing spaces equipped with lamps that mimic natural light.
Any of these seeds is capable of producing top-quality crops indoors if the lighting, ventilation, tidiness and cleanliness conditions are just perfect. As important as the use of adequate lamps is the ability to control them using timers that regulate the daily hours of light and of darkness each seed needs.
Most of the genetics regarded as suitable for growing indoors are Indica-dominant. Pure Sativas or Landrace Sativas are not adequate since they have a long flowering phase and easily run out of space within the growing tent. Although autoflowering marijuana plants are a great option too, their XXL versions are best grown outdoors.
All indoor cannabis seeds can also be cultivated outdoors, as long as the environment is sufficiently warm and sunny.

Pros and cons of growing marijuana seeds indoors
Indoor marijuana seeds for sale are an attractive option for growers of all levels, but they’re not a one-size-fits all solution. There are advantages and disadvantages to consider before making an informed purchase decision.
Keeping your marijuana indoors provides security, shelter, and stealth. On the other hand, your plants remain small, and you don’t get to experience the extreme yields of outdoor giants.
In a nutshell, here are the benefits of growing the best indoor marijuana seeds :
- Better control of all conditions
- Easy protection from potential issues
- Greater privacy and discretion
- Perpetual harvest potential
Some people still choose outdoor setups, though. Here are the comparative disadvantages of indoor cultivation :
- More expensive to set up
- No access to real sunlight
- Less microbial life
In a nutshell, indoor seeds take the gold if you can afford the investment . Let’s explore the perks in a bit more depth.
Save time with quick & easy harvests
Photoperiod cannabis crops in the great outdoors rely on changing the seasons to switch between its three life stages. As a result, the seed-to-harvest period usually takes over six months, from early spring to early fall.
Feminized indoor marijuana seeds develop into ripe crops in much less time. Flowering time is strain-dependent and should be respected, but you can half the vegetative stage .
This phase is when your crop produces branches and foliage, not buds and resin. Indoor growers can switch the lights for flowering after several weeks of vegging. That way, you get small plants without too many unnecessary branches.
A six-month life cycle is suddenly four months long , and there’s less trimming struggle along the way.
Combine this perk with our cannabis seeds for beginners , and your cultivation journey becomes a walk in the park.
Control your environment
Environmental optimization is the number one reason why many growers choose indoor seeds . Why use clones to ensure the best possible phenotype? Let each seed develop to perfection with a helping hand instead.
The outdoors brings unexpected waves of low light conditions and increased humidity, pests, disease, and other cultivation pitfalls.
It’s a different story inside. You’re in charge of the environment, letting you fine-tune the conditions. Get the right lamps, filtration systems, and nutrients for marijuana .
Use these modern tools to boost the bulk and quality of every future harvest .
Mimic the outdoor conditions, minus the bad stuff. Your rare tropical strain can easily thrive in a cold state—just up the heating and moisture. Those adaptable indica crops appreciate the lack of climate fluctuations, even if they technically could withstand them.
Never worry about infestations
Your outdoor garden is full of little bugs that find cannabis leaves a treat they can’t refuse. You could stay vigilant, plant companions in the surrounding soil, and install protections. Alternatively, keep your marijuana indoors and nip this problem in the bud .
A sealed and sterile grow room runs little risk of infestation. Even if something does slip through the cracks, the adverse effects are less severe.
Grow whenever and wherever you want
This selling point of best indoor marijuana seeds started with commercial growers but quickly spread to everybody else. Why smoke six-month-old buds when you can always have the freshest flower in your stash?
Growing cannabis inside doesn’t leave you dependent on the growing season . Sow in December and collect in March. Repeat two more times in a calendar year.
As a bonus, you don’t have to worry about nosy neighbors noticing your crop and giving you weird looks. Indoor setups let you forget all about a lack of garden space or proper shielding to keep it private.
Where to grow indoor weed seeds?
The stellar genomes of our indoor seeds make them suitable for various systems. As long as your space is clean, secure, and adaptable , you can choose whichever setup best fits your situation.
As a rule of thumb, seal the cultivation unit to prevent pests from harassing your crops. Install a ventilation system to provide fresh air to your budding plants. Get lamps to mimic outdoor sunlight—even indoor strains need light.
What growing arrangements are available? Our community goes for the following:
- Closets are convenient but far from optimal. Opening and closing the doors can disrupt the light cycle, and the air gets stuffy. Stick to one plant if closet-growing.
- Space buckets fit a single plant but provide a stable growing environment. Pick a short indoor strain for the purpose. The same rules apply as with closets, but the results tend to be much better.
- Grow tents can hold anywhere between two and ten indoor plants. These neat devices promise excellent light distribution and protection.
- Grow boxes are an alternative to a tent you make at home. Choose a sturdy wood or metal base and reflective material with a zipper for the insides.
- Windowsills are excellent for tiny crops, but they reduce harvest potential. Supplement lights with LEDs and introduce temperature control to improve this setup.
- Grow rooms are the top choice for dedicated cultivators. Having an entire chamber for your indoor marijuana seed -grown crops eliminates the downsides you’d face with other options.
